Abstract

"We are going to make a spiral 100 candle power lamp and treat it so as to give 150 candles and try it in place of calcium light. As I think I have recently mentioned money to you, I will only add that we need some extremely. Insull says you are making an effort, yet we have not yet felt the fruits of it."
